Jessica Simpson And Lauren Conrad Flash Their Fashion Stripes

Jessica Simpson in a printed dress and Lauren Conrad in a silk shirt and skirt

Hayden Panettiere, Paris Hilton, Petra Nemcova and Lauren Conrad were just a few of the hot A-listers papped at the US Weekly Hot Hollywood 2011 party last night. Jessica Simpson, who was crowned Style Icon Of The Year at the exclusive event, showed off an enviable trimmer figure (pre-wedding diet, perhaps?) in a power-print mini and mega eye-watering platforms – you wouldn’t want to take a trip in those bad boys! And The Hills’ Lauren Conrad looked effortlessly gorgeous in a silky blouse and skater skirt combo (see Lauren Conrad's fab fashion file below). We’re totally lusting after her huge ballerina topknot hairstyle – so much so, we believe it might just be the updo we’ve been looking to rock for the royal wedding. We’re off to start practising!
